Basel, February 2026

Zirkular GmbH, based in Basel, has launched its new platform , rematerial. According to a press release, the new online DIY store will offer high-quality, reusable building components. For example, it will offer LED lights that have been reconditioned by specialist companies and now come with a guarantee. Components can also be reserved for a month or stored temporarily for up to 24 months for just-in-time deliveries. The building components collected from demolition sites are stored in a systematic manner.

The rematerial platform can be used in conjunction with thePlanularplanning tool, which was also developed by Zirkular. In this module, architects, planners and builders can select the components required for their respective projects from a database. The path of the building material can be traced through the steps of source object, component, warehouse and target object.

With both modules, Zirkular GmbH supports sustainable construction through circular economy, as demonstrated, for example, in construction projects such as the Lysbüchel Süd neighbourhood in Basel.
